I think 10 kg sounds pretty good.
I recently did the Overland Track over Christmas, and a lot of research on equipment and base weight leading up to it. (I couldn't do as much actual trial runs due to having a 2.5 year old at that time - she's since turned 3, and it's the awkward age between being independent and not wanting to be in a baby carrier but also not up to walking far in a straight line without getting distracted and stopping to look at stuff and linger for ages.)
I came to the conclusion for myself that...
IT'S RELATIVELY EASY TO GET TO A COMFORTABLE 7 KG "ish" BASE WEIGHT
I'm a comfort queen and my set-up included a very heavy 1.2 kg sleeping mat which is supremely comfortable, and which I did try and switch out for a Thermarest NeoAir XLite in trial runs but I couldn't sleep with the crinkly noise - I'm just too sensitive. But if I switch to a less heavy mat, that would drop close to 1kg off my set-up, which would then be about 7 kg.
Overland Track hike set-up here:
https://www.lighterpack.com/r/bz0cqfYOU CAN GET DOWN TO 5 KG BASE WEIGHT... BUT TO ACCOMPLISH THAT, TYPICALLY NEED ULTRALIGHT BACKPACK (400- 700 grams "ish"), ULTRALIGHT SHELTER (400-700 grams "ish"), ULTRALIGHT MAT (200-400 grams "ish"), DOWN QUILT (500-600 grams "ish")
I've drafted myself up a hypothetical sub-5kg base weight set-up, which also includes links in the notes to some other backpackers set-ups which are around that sub-5 kg base weight for inspiration and reference.

However as noted by others, base weight is not the only focus because far more important than that is:
Q1) What are the conditions you're going out into, and what is the range of what can you expect for that time of the year. Cold? Buggy? Wet? Animals that can eat your food? Safety / Navigation equipment required? How much water storage are you going to need?
There is such as thing as going "stupid light" which is being so overly focused on base weight and cutting gear out of your pack, that you end up dangerously without something you need for the conditions or warmth or rain protection that you need for the conditions, etc. The famous adventurer Andrew Skurka describes himself going out on an adventure where he was trying to do it really light and fast, and going without a sleep quilt to save weight thinking he could sleep in his puffie jacket. He ended up cold, shivering, unable to sleep... perfect example as he says of going stupid light.
Q2) What works for someone else may not work for you. aka "Hike your own hike"
Comfort wise - Some people can sleep on a lightweight CCF (closed cell foam) pad, others can't.
Temperature wise - Some people are small or slim and sleep cold, and need a higher R value (higher insulation) pad to sleep comfortably.
Food wise - Some people are happy to eat functionally going entirely off calories and not taste. Some people happy to take an peanut butter plastic jar and cold soak couscous for example, with a bit of dehydrated vegetables in the mix. And take energy bars and dry snacks. And going entirely stoveless. Others value a hot meal and definitely want to take a stove for a hot meal at the end of the day, and hot drinks and/or porridge.
Money - and how much you want to splurge. One of the easiest ways to get weight down is if you can throw a lot of money at it, you can get a Dyneema composite tent at around 450 grams for a 1 person tent or 560 for a 2 person tent. And a Dyneema or ultralight backpack at around 400-600 grams ish.
Now looking at your set-up, it all looks like good stuff to me, and relatively lightweight.
You could shave weight if you really want to throw money at a lighter tent.
You could shave a bit of weight of your rain set-up.
I don't know the break-down of your insulation layers to comment on that (as in what are the individual pieces making up that weight?) and it's possible that you could save weight but I wouldn't want to say that without seeing what they are exactly.
But basically looks good!
